Could this be a similar problem as observed in bug 53498, comment 1?

Indeed, the testcases look similar and the stack traces are both infinite recursions that ping-pong between the same 2 functions. Thanks.

template class U, class... V
static void test(U * u, V *... v,
decltype(u-update(*v...)) * = 0);
};

crashes g++-4.8 -std=c++11 from 1 month ago (can't test current right now).

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53545 --- Comment #3 from Anthony Hall squidbidness at gmail dot com 2012-06-01 04:29:26 UTC --- For what it's worth, I discovered the file will successfully compile (with the same compilation command as in original report) if I move the FirstStep, SecondStep, Yes, and No utility templates and specializations out of the HasUpdateMethod to file scope, or embed them in a file-level detail namespace, with no other code changes.
